We describe generalized running key ciphers and apply them for analysis of two Shannons methods. In particular, we suggest some estimation of the cipher equivocation and the probability of correct deciphering without key.
Elaborate protocols in Secure Multi-party Computation enable several participants to compute a public function of their own private inputs while ensuring that no undesired information leaks about the private inputs, and without resorting to any trust
How to enhance the communication efficiency and quality on vehicular networks is one critical important issue. While with the larger and larger scale of vehicular networks in dense cities, the real-world datasets show that the vehicular networks esse
The advances of the Internet of Things (IoT) have had a fundamental impact and influence in sharping our rich living experiences. However, since IoT devices are usually resource-constrained, lightweight block ciphers have played a major role in servi
This article serves as a brief introduction to the Shannon information theory. Concepts of information, Shannon entropy and channel capacity are mainly covered. All these concepts are developed in a totally combinatorial flavor. Some issues usually n
Since their introduction over two decades ago, side-channel attacks have presented a serious security threat. While many ciphers implementations employ masking techniques to protect against such attacks, they often leak secret information due to unin
